Security company ad on TV-
"We will guard your home with 24-hour continuous video recording of your property. Any criminal activity will be recorded."
One day a customer of the advertised security system gets robbed. Customer calls the security company -
"Can you please pull the video from the incident last night when our home was burglarized"
Response from security company -
"We are sorry but our 24-hour continuous recording of the property only provides one image per hour. We are sorry to regret that the robbery took place outside of that time frame. Please have a nice day."
Again, the bias on this forum is profoundly deafening. :smile:
Technically, even a continuous video is
24 or 30 times per second. This same "continuous video" is insufficient for analyzing a car crash slow motion type capture while it is sufficient for recording a robbery. Why? Because robbers don't move faster than 30 times per second while a car does. So When MSFT band takes many HR samples per minute, it is sufficient to track HR variations and dynamics for the band's specific and advertised health features. And in exercise mode, it goes all-in as the HR changes rapidly.
I really hope you stop playing the bias card and discuss science and technicality. I am merely trying to share my knowledge and experience with you politely and with patience because I personally think expecting more from a product is a consumer's right and should be executed, however
giving out misinformation that this product does one HR sample per hour is factually incorrect and quickly becoming a distraction. The device
displays hourly data averaged from many many BPM estimates it made during that hour.
If you still think this information has been biased, I apologize. I tried hard to simply lay out facts about hardware as an engineer and I have failed to explain you what sampling rate has to do with calling a sensor continuous.
